A bear named Paddington (Ben Wishaw), once arrived in England from the dense Peruvian forest, lives happily in the family of Mr. and Mrs. Brown. Wherever he went, the bear cub always gives joy and marmalade to those around him. Paddington became an honorary member of the local community and even got a job to buy his beloved aunt Lucy (Imelda Staunton), who turns 100 years old, the perfect gift for the anniversary. Once he finds an incredible book in the antiques store and decides to buy it. But soon the book is stolen, and Paddington turns to the family of Browns for help, so that they help him find and expose the thieves.
